§ 1

Numbers by the formula

Nominal 265/70R17 numbers come from the size math. Overall diameter is 31.6 in (803 mm). Section width is 10.4 in (265 mm). Sidewall height is 7.3 in (186 mm). Rim diameter is 17 in (432 mm).

Circumference is 99.3 in (2,522 mm). Revolutions per mile are 638 (396 per km).

  • Overall diameter: 31.6 in (803 mm).
  • Section width: 10.4 in (265 mm).
  • Circumference: 99.3 in (2,522 mm); 638 revs per mile (396 per km).

§ 2

Published measurements

Makers list 33 tires in 265/70R17 from 5 brands: Kumho, Firestone, Nitto, Toyo and Mickey Thompson. The set includes 21 LT and 12 P-metric versions. Published overall diameters run 31.6 in to 32.0 in against 31.61 in by the formula (0.0% to +1.2%).

Weights in the published set run from 36.3 lbs to 61.5 lbs. New tread depths run 12/32 in to 19/32 in. Manufacturers publish approved rim widths and maximum loads; federal rules require rim listings (49 CFR 571.139).

  • Kumho Road Venture RT LT265/70R17 — diameter 31.6 in; measuring-rim width 10.7 in; weight 54.6 lbs; tread 17.3/32 in.
  • Toyo Open Country A/T III LT265/70R17 — diameter 31.7 in; overall width 10.7 in; weight 48 lbs; maker lists 656 revs per mile.

§ 3

Close alternate sizes

The neighbor table uses a ±3% overall-diameter window. The ±3% window is a tire-shop rule of thumb, not a law. Sizes within 3% on rims from 16 to 18 in include 265/65R18, 265/75R16, 285/70R16 and 245/75R17.

Small diameter changes give small speedometer, axle clearance and revs-per-mile effects. For calculations use the speedometer calculator or the comparison tool.

  • 265/65R18 — diameter −0.1% (−0.04 in, −1 mm); indicated 60 mph → true 59.9 mph; revs 638 → 639.
  • 265/75R16 — diameter +0.1% (+0.04 in, +1 mm); indicated 60 mph → true 60.1 mph; revs 638 → 637.
  • 285/70R16 — diameter +0.3% (+0.10 in, +3 mm); indicated 60 mph → true 60.2 mph; revs 638 → 636.

Q&A

Common questions

What is the overall diameter of 265/70R17?

By the formula the overall diameter is 31.6 in (803 mm). Makers' published diameters run from 31.6 in to 32.0 in.

How many revolutions per mile does it make?

Nominal revolutions per mile are 638 (396 per km). Toyo lists 656 revs per mile for its Open Country A/T III in this size.

Are LT and P-metric versions available?

Yes. Maker tables list 33 tires with 21 LT and 12 P-metric versions. Published load ranges include SL, XL and E.

Where do I find vehicle load and inflation information?

See the tire and loading placard on the driver's side B-pillar for the vehicle maker's recommended cold inflation pressures (49 CFR 571.110). Read the tire sidewall for the tire's maximum load rating and, for LT tires, the load range letter (49 CFR 571.139).

Notes

Method and sources

Each number and rule comes from a source with the date it was checked.

  1. Sidewall = width × aspect ratio ÷ 100
  2. Diameter = rim × 25.4 + 2 × sidewall (mm)
  3. Revs per mile = 63,360 ÷ (π × diameter, in)
  4. True speed = dial × new diameter ÷ old diameter
  5. Clearance change = half the diameter change

Numbers are nominal: the tire unloaded, on its measuring rim. Revs per mile published by makers run higher than the formula. “Within 3%” is a rule of thumb tire shops use, not a law. Tire pressure: the placard on your door jamb.
